The Cobra Dual-Channel Flexible Ureteroscope: Novel Function, Novel Applications

A Dual-Channel Flexible Ureteroscope: Evaluation of Deflection, Flow, Illumination, and Optics

“…7 In one case, the working channel was used to deploy a stone basket to secure a renal stone in a hydronephrotic kidney while the laser fiber was deployed through the secondary channel. In a second case, a sessile urothelial tumor was held on traction by a stone basket placed through the working channel while the laser fiber deployed through the secondary channel was used to transect the base of the tumor.…”

Instrumentation in endourology

“…They noted that the dual-channel scope provided superior flow and deflection when larger instruments were deployed. In addition, they reported utilizing the second channel to stabilize stone or tissue while laser ablation was applied through the dedicated laser channel [Ortiz-Alvarado et al 2010].…”
